“The rise in seaborne trade was the most important reason for the decline of the Silk Road in the 15th century.” To what extent do you agree with this statement?

Candidates are required to consider the merits or otherwise of the argument that the rise of seaborne trade was the most important reason for the decline of the Silk Road in the 15th century. In support of the argument candidates may discuss the impact of the voyages of Zheng He, which opened up seaborne trade with India, Africa and the Middle East. This was quicker and more secure than the land alternative. The voyages of Dias and da Gama came too late to influence trade before 1500. Candidates may consider the importance of other factors, for example, the steep decline in the silk trade, the Chinese policy of “turning in”, the threats from nomadic tribes and the fragmentation of the Mongol Empire which made the Silk Road more hazardous.
